wxPython – wx.RadioBox 中的 FindString()函数
在本文中,我们将学习与 wxPython 的 wx.RadioBox 类关联的 FindString()函数。 FindString()函数仅用于查找与给定字符串匹配的按钮,如果找到则返回位置,如果未找到则返回 NOT_FOUND。
它需要一个字符串参数来匹配字符串,否则需要布尔 bCase True 来表示区分大小写的 False。
Syntax: wx.RadioBox.FindString(self, string, bCase=False)
Parameters:
Parameter | Input Type | Description |
---|---|---|
string | string | The string to find. |
bCase | bool | Should the search be case-sensitive? |
Returns: Returns the index of matching button starting from zero.
Return Type: int
代码示例:
import wx
class FrameUI(wx.Frame):
def __init__(self, parent, title):
super(FrameUI, self).__init__(parent, title = title, size =(300, 200))
# function for in-frame components
self.InitUI()
def InitUI(self):
# parent panel for radio box
pnl = wx.Panel(self)
# list of choices
lblList = ['Radio One', 'Radio Two']
# create radio boc containing above list
self.rbox = wx.RadioBox(pnl, label ='RadioBox', pos =(80, 10), choices = lblList,
majorDimension = 1, style = wx.RA_SPECIFY_COLS)
# print the position of matching string button
print (self.rbox.FindString('radio two'))
# set frame in centre
self.Centre()
# set size of frame
self.SetSize((400, 250))
# show output frame
self.Show(True)
# wx App instance
ex = wx.App()
# Example instance
FrameUI(None, 'RadioButton and RadioBox')
ex.MainLoop()
